Abstract
The invention relates to an energy-saving universal motor which has the same size with a three-phase asynchronous motor with the same power. A rotor core is processed into an H shape, a rotor winding is wound around the rotor core, and a stator is still a three-phase winding. The rotor winding can be connected a the stator winding in series or in parallel, or can supply power independently. Stator and rotor power supply can be single-phase alternating current and can also be direct current. Both the stator winding and the rotor winding produce magnetic fields after being energized, and the magnetic axes of the magnetic fields of the stator winding and the rotor winding keep orthogonal under the action of a detecting disk and corresponding electronic switch or under the cooperation of a slip ring brush assembly so as to produce greater torque. The rotary speed of the rotor is independent to supply frequency, and the stepless speed adjustment can be realized by regulating supply voltage. Because the magnetic axes of the magnetic fields of the stator and the rotor keep orthogonal, the power factor cos phi is equal to 1, and thus, compared with the three-phase asynchronous motor, the energy-saving universal motor has certain energy saving effect. Moreover, when the supply frequency is increased, the rotary speed of the motor is not influenced, the size can be relatively reduced, and materials are saved.
Description
Affiliated field
The invention belongs to electric motors.
Background technology
The threephase asynchronous that is widely used at present, its operation principle is, three winding mechanical angles of stator and electrical degree be 120 ° of mutual deviations all, stator winding produces rotating magnetic field after inserting three phase mains, magnetic flux cutting cage-type rotor sliver, form rotor current, the electromagnetic torque that the stator rotating magnetic field produces promotes the rotation of current-carrying rotor.Its rotating speed and supply frequency are closely related.The present invention is that rotor winding and stator winding all insert single phase alternating current (A.C.) or DC power supply, makes the magnetic axis of rotor field and stator field magnetic axis keep quadrature with electronic switch or carbon brush slip-ring group, thereby makes stator and rotor keep big electromagnetic push.Because electromagnetic force is only relevant with winding size and size of current and magnetic flux density, irrelevant with supply frequency, the adjustment of its rotating speed only need change supply voltage.If adopt high frequency electric source also can dwindle the motor volume economical with materials.When alternating current moves, stator and rotor quadrature power factor COS φ=1, thereby the consumed power of motor is reduced to some extent.
Summary of the invention
Motor stator coiled two utmost points six phase windings are concatenated into three-phase; Rotor core is processed into " worker " font and is wound the line, and winding is drawn through collector ring.
Use rotor position detector, make electronic proximity switch provide signal, control exchanges or electronic DC switch makes stator and rotor magnetic field magnetic axis keep quadrature.
Or with the metal part lease making carbon brush energized of slip ring, the insulated part deenergization guarantees stator and rotor magnetic field magnetic axis quadrature.
The technical problem that solves
The present invention solves its technical problem two schemes: first scheme, on insulation glass plate, paste a semi-round ring shape (170 °) stainless steel thin slice, and make the center line of ring and rotor core " worker " font central lines and the glass plate is fixed in the rotating shaft.Fix a glass plate (mesopore does not influence rotating shaft greater than the rotating shaft diameter and rotates) in stator faces, install 6 on the glass plate near switch, 60 ° of switch gaps, it is identical with the stainless steel semicircular ring that radius is installed, near corresponding place of central channel between per two windings of three windings of stator, position of switch.Rotor at an arbitrary position, the stainless steel ring correspondence will respond to output signal near switch, open corresponding electronic switch and make rotor winding and corresponding stator winding energized, produce electromagnetic push.Electronic switch can be made by alternating-current switch (4 diodes add a power transistor, or bidirectional triode thyristor type solid-state relay), also can directly make (during direct current supply) with power transistor.
Alternative plan is installed slip ring in rotating shaft, the slip ring material is a nylon rod, and a stainless steel substrates (170 ° of semicircle arc length), the center line of arc length and rotor " worker " font central lines are pasted in its surface.Fix a glass plate in stator faces, carbon brush be installed thereon, the position and first scheme near switch with.The power supply of this scheme can be to exchange, and can be direct current also, but has spark to produce.
Beneficial effect
The invention has the beneficial effects as follows, motor adopt single phase poaer supply power supply and AC and DC all can, rotating speed is easy to adjust, changes supply voltage and gets final product; Certain energy-saving effect is arranged; Can reduce volume during the high frequency power supply, save material.
